32 disc-like pieces that have to be grouped in six groups of four pieces on two rings.
This puzzle consists of two rings, one front, one back. These rings contain 32 small disc-like pieces. Each has a different colour on the front and back.
The turnable rail in the middle allows single discs
-to be rotated.
-to be moved to the other ring.
-to be moved to another slot in the same ring.
The goal is to find out the colour configuration of every disc and then sort and orient the discs to the two rings. In the result both rings have to consist of three groups of four discs in the same colour.
